梦瑶 发自 凹非寺 量子位 | 公众号 QbitAI 救命,现在的AI,光会帮我下单已经不够了。 连免单、发红包都要一并安排上???(还有这种好事儿) 咱先来说说千问这次搞的是个啥活动。 直白点说就是:趁着 2月6日 春节节点,千问打算让AI陪大家热闹一把,具体形式呢,就是——砸钱!!! 你还别说,真有。 今天,千问官宣了一个 "春节请客计划" :打算自掏腰包 3 0亿 。 目标嘛:直接包揽全国人民的吃!喝!玩!乐! 这还没完呢,千问这次是带着兄弟团来的,淘宝、飞猪、盒马、大麦……这次全都变身成了千问的办事帮手~ 说实话,这应该是阿里史上投入最狠的一个春节了,放到今年这场大厂AI春节大战里,也是金额直接拉满的那种。 前脚我还在感叹:AI已经能帮我点外卖、做攻略、安排行程了。 结果才过了半个月,它连「钱」这一步都顺手替我掏了…… 红包、免单一起上,千问强势入局春节AI大战 是的,千问准备拿出「30亿」,通过 免单 的方式直接请大家吃喝玩乐。 说实话,消息出来之后,我第一反应倒不是说这得投入多少钱,而是心里咯噔一下:坏了,AI这进化的速度,已经快到我反应不过来了…… 要知道,距离我上一次让千问帮我下单27杯霸王茶 ...
何恺明带大二本科生颠覆扩散图像生成:扔掉多步采样和潜空间,一步像素直出
量子位· 2026-02-02 05:58
Core Viewpoint - The article discusses the introduction of a new method called Pixel Mean Flow (pMF), which simplifies the architecture of diffusion models by eliminating traditional components like multi-step sampling and latent space, allowing for direct image generation in pixel space [2][3][5]. Group 1: Methodology and Innovations - pMF achieves significant performance improvements, with a FID score of 2.22 at a resolution of 256×256 and 2.48 at 512×512, marking it as one of the best single-step, non-latent space diffusion models [4][27]. - The elimination of multi-step sampling and latent space reduces the complexity of the generation process, allowing for a more efficient architecture [6][36]. - The core design of pMF involves the network directly outputting pixel-level denoised images while using a velocity field to compute loss during training [13][25]. Group 2: Experimental Results - In experiments, the pMF model outperformed the previous method EPG, which had a FID of 8.82, demonstrating a substantial improvement in image generation quality [27]. - The addition of perceptual loss during training led to a reduction in FID from 9.56 to 3.53, showcasing the effectiveness of this approach [26]. - The computational efficiency of pMF is highlighted, as it requires significantly less computational power compared to GAN methods like StyleGAN-XL, which demands 1574 Gflops for each forward pass, while pMF-H/16 only requires 271 Gflops [27]. Group 3: Challenges and Future Directions - The integration of single-step and pixel space models presents increased challenges in architecture design, necessitating advanced solutions to handle the complexities involved [10][12]. - The article emphasizes that as model capabilities improve, the historical compromises of multi-step sampling and latent space encoding are becoming less necessary, encouraging further exploration of direct, end-to-end generative modeling [36].
OpenClaw们狂奔,谁来焊死安全车门?
量子位· 2026-02-02 05:58
Core Viewpoint - The article emphasizes the transition of AI from a capability-first approach to a trust-first paradigm, highlighting the importance of security in the development and deployment of intelligent agents [4][50]. Group 1: Intelligent Agent Security Framework - The intelligent agent security framework proposed by Tongfudun consists of three layers: foundational, model, and application layers, which are essential for ensuring the safety and reliability of AI systems [11][14]. - The foundational layer focuses on computational and data security, ensuring the integrity of the AI's "body" and the purity of its data [12]. - The model layer emphasizes algorithm and protocol security, providing the AI's "mind" with verifiable rationality and aligned values [12]. - The application layer involves operational security and business risk control, applying dynamic constraints and evaluation mechanisms to the AI's real-world actions [12]. Group 2: Node-based Deployment and Data Containers - Node-based deployment offers a resilient infrastructure paradigm by decentralizing computational power into independent, trusted execution environments, thus mitigating single points of failure [16][17]. - Data containers serve as the core vehicle for data sovereignty and privacy, integrating dynamic access control and privacy computing capabilities to ensure data remains "available but invisible" during processing [21][23]. - The combination of nodes and data containers aims to create a scalable collaborative network of intelligent agents, enhancing their autonomy and security boundaries [25][27]. Group 3: Formal Verification and Algorithm Security - The concept of "superalignment" aims to ensure that AI's goals and behaviors align with human values, with a focus on model and algorithm security [29]. - Formal verification is being integrated into the algorithm security framework to mathematically prove that the AI's decision-making logic adheres to defined safety requirements [34][38]. - This approach addresses the inherent unpredictability of AI behavior by establishing clear, provable safety boundaries, thus enhancing the overall security of intelligent systems [36]. Group 4: Application Layer Security Challenges - The rise of "action-oriented" intelligent agents, such as OpenClaw and Moltbook, signifies a shift towards autonomous execution, which introduces new security threats that traditional protective measures cannot address [41][43]. - The security risks include the potential for agents to be manipulated into unauthorized actions through prompt injections, highlighting the need for advanced risk control paradigms [44][45]. - Tongfudun's ontology-based security risk control platform transforms domain knowledge into a machine-understandable semantic map, enabling real-time risk assessment and compliance verification [45][48]. Group 5: Trust as a Foundation for AI Development - The transition from a capability-first to a trust-first mindset is crucial for the sustainable development of AI, particularly as intelligent agents become central to human-machine interactions [50][51]. - The establishment of a "trust infrastructure" for the digital world is essential for unlocking the potential of the intelligent agent economy, comparable to foundational technologies like TCP/IP and encryption in the early internet [51]. - Companies leading in this security domain will not only mitigate risks but also define the next generation of human-machine collaboration rules and build trustworthy commercial ecosystems [54].

大模型API的大众点评来了:7×24小时实测,毫秒级延迟智能路由,选API必备
量子位· 2026-02-02 03:39
你说荒诞不,在API调用动辄几十万、上百万token的时代, API选型居然变成了一件靠经验反复试错的事儿 。 这就导致想要接个API做开发,还得先被迫兼职下采购员。东市买骏马,西市买鞍鞯,必须把市面上的供应商挨个测一遍。 (写到这儿的时候,我的表情就是那个大家可以想象的痛苦面具闭眼表情包.jpg) 衡宇 发自 凹非寺 量子位 | 公众号 QbitAI 忍不了了,这个槽我真的不吐不快! 比面对大模型黑盒更让人抓瞎的事情,就是要去选既靠谱、性价比又高的API服务 。 这几乎是每一个涉足AI应用开发的团队都会经历的至暗时刻,抹泪.gif。 同一个模型架构在不同的供应商手里,不仅价格上有出入,延迟、稳定性、吞吐量等用户关心的指标,波动幅度简直堪比霸天虎过山车。 不er,就没有一个工具能把这些API的底裤扒得干净,让咱开发者省点心吗? 带着如此沉痛的心情跟周围人打听了一圈,你还真别说,有人告诉我有家 清华系的AI Infra公司——清程极智 ,真就做了这个事儿。 产品叫AI Ping,之前没做过什么宣发,基本一直就靠口碑口口相传。 用一句话来概括功能,可以说它就像 大模型API领域的大众点评 。 用7×24小时持续运 ...
